BACKGROUND

Overview of Cloud Computing

Cloud computing services such as Amazon EC2 and Windows Azure are becoming more and more popular but it seems many people are still unclear as to what exactly the buzzword “Cloud computing” actually means. In its simplest form, the principle of
Cloud computing is the provision of computing resources via a network.
Cloud Computing has become one of the most talked about technologies in recent times and has got lots of attention from media as well as analysts because of the opportunities it is offering. The market research and analysis firm IDC suggests that the market for Cloud Computing services was ` 68000 crore in 2008 and will rise to `178500 crore/year by 2012 [1]. It has been estimated that the cost advantages of Cloud Computing to be three to five times for business applications and more than five times for

    Cloud computing is the answer for “affordable” business technology platforms. It is a more affordable solution for media content than any other medium, and this is why Netflix, Amazon.com, and Apple are among the leaders in cloud usage and development. Ultimately cloud computing will be the primary way data services are accessed by businesses and consumers alike. Marston, Li, Bandyopadhyay, Zhang, and Ghalsasi 2009 conclude cloud computing offers companies the opportunity to deploy cutting edge IT services without the enormous upfront costs that deter so many organizations from making the investment in infrastructure. Now that affordable solutions are becoming more readily available it is likely that more small and medium sized businesses will try and streamline their IT services. Small and medium sized businesses will likely be attracted to billing features that only charge for actual usage, as opposed to a flat fee.…

    “Every kid coming out of Harvard, every kid coming out of school now thinks he can be the next Mark Zuckerberg, and with these new technologies like cloud computing, he actually has a shot” (Andreessen, 2012). Cloud computing is what allows businesses today to pay for what is only consumed. This access to real time computing environment that extends information technology infrastructure of a company’s capabilities is unprecedented. Companies who have to use expensive capital cost and employee labor costs to spin up a working infrastructure that a company could use to go to market. The National Institute of Standards and Technology defines the cloud as “a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction” (Engle, 2012). This would also add time to how rapidly the business could get to market. This sustainable competitive business advantage is important for businesses to stay relevant into today’s marketplace. Now businesses can access this computing infrastructure quickly and cheaply without a significant startup costs. Cloud computing will and has changed the game forever. With this information building a career in cloud computing will be the cornerstone of the future technologist resume.…

    Technology has taken great leaps of advancement. Some of the new technology that companies and consumers are taking advantage of to store and process data is cloud computing. Cloud computing was derived from virtualization. Virtualization allows companies to separate business applications from hardware. Doing this gives the company the capability of assigning applications as needed. The option to manage applications is a great benefit to companies. Resulting from the virtualization error, cloud computing has emerged to provide flexible IT infrastructures. This has not only enhanced the options companies now have, but it is also proven to be more cost efficient. This has increasingly become a preferred method of companies and consumers alike.

    With the unprecedented growth and spread of information, there is no wonder why large Information Technology companies have been investing in the “cloud”. To expand, when referring to Cloud Computing, this means to access and store information not stored with in your computer whether it be public, private, or hybrid cloud computing. In technological terms, the server you are accessing is somewhere else and therefore, the information and tools you are using are “up in the clouds” but more so stored in another server space. However, whether you are paying for services through software, total usage, or free usage (hence the types of cloud services) Cloud Computing seems to be everywhere. Yet, it is important to recognize what is to gain by using cloud computing from big businesses to individual users and what are some risky moves when utilizing cloud storage over the Internet. Hence, the content of this paper will discuss the pros and cons of cloud computing and where cloud computing is headed in todays online society.…

    IT departments and infrastructure providers are under increasing pressure to provide computing infrastructure at the lowest possible cost. In order to do this, the concepts of resource pooling, virtualization, dynamic provisioning, utility and commodity computing must be leveraged to create a public or private cloud that meets these needs. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. This provides the smaller companies or individuals who couldn’t able to buy costly software or any other resources. This becomes easy because of cloud computing. Cloud promises real costs savings and agility to customers. It’s a ‘Pay for Usage’ plan. We pay the money based on our usage only.

    As with any new trend in the IT world, enterprises must figure out the benefits and issues of cloud computing and the best way to use this technology. Cloud computing is “a general term for anything that involves delivering hosted services over the Internet.” (Rouse, 2010, para. 1). Cloud computing consists of three different types of services: 1) Infrastructure as a Service (IaaS), 2) Platform as a Service (PaaS), and 3) Software as a Service (SaaS). (Laudon & Brabston, 2012). “A cloud may be private or public. A public cloud is maintained by an external service provider accessed through the Internet, and available to the general public. A private cloud is a proprietary network or a data centre that ties together servers, storage, networks, data, and applications as a set of virtualized services shared by users inside a company. Like public clouds, private clouds are able to allocate storage, computing power, or other resources seamlessly to provide computing resources on an as-needed basis” (Laudon & Brabston, 2012). Infrastructure as a Service like Amazon web services provides customers with “processing, storage, networking, and other computing resources from cloud service providers to run their information systems” (Laudon & Brabston, 2012). Platform as a Service “is defined as a set of software and product development tools hosted on the provider’s infrastructure” (Rouse, 2012, para. 5). Software as a Service provides customers to “use software hosted by the vendor on the vendor’s hardware and delivered over a network” (Laudon & Brabston, 2012).…

    Will the cloud have as big an impact as many predict? A complex question. Cloud computing is available now; it’s already changing the manner in which IT and business services are delivered and managed. But as is often the case with new technologies, organizations may overestimate the short-term effects while simultaneously underestimating the long-term benefits. Without understanding the larger wave of IT developments of which the cloud is just a part, companies may invest in capabilities that will not pay off sufficiently—potentially compromising their competitiveness as time goes on.…

    Cloud computing is a colloquial expression used to describe a variety of different computing concepts that involve a large number of computers that are connected through a real-time communication network (typically the Internet). Cloud computing is a jargon term without a commonly accepted non-ambiguous scientific or technical definition. In science, cloud computing is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time. The popularity of the term can be attributed to its use in marketing to sell hosted services in the sense of application service provisioning that run client server software on a remote location.…
